Product Description
Long weld neck flange is a type of flange with a higher neck height, which improves the stiffness and load-bearing capacity of the flange. Compared with butt welding flanges, long neck flanges require a larger welding workload, higher electrode consumption, and cannot withstand high temperature, high pressure, repeated bending, and temperature fluctuations. However, its on-site installation is relatively convenient and can omit the process of welding and rubbing, making it popular in practice.
The main characteristics of long weld neck flanges are as follows:
1.Strong corrosion resistance
2.Sturdy structure
3.Easy to install
4.Size standard
5.Wide applicability

Note1:Dimensions N1,N2and N3 are measured at the intersection of the hub draft angle and the back face of the flange.Note2:For d1 dimensions see document "Flange Facing Dimensions parameter table "
Long neck welding flanges are commonly used in industries with high pipeline requirements and suitable for high temperature and high pressure conditions, such as chemical, petroleum, natural gas, etc. Meanwhile, the characteristics of long neck welded flanges are also applicable to industries such as textiles, food, and shipbuilding.
